Understanding the near-threshold structures in $e^{+}{e}^{-}$ annihilation from a unified $N\bar{N}$-interaction perspective

Teng Ji, Ulf-G. Meißner

Near-threshold structures have been observed in the cross sections for $e^{+}{e}^{-}\to p\bar{p}$, $e^{+}{e}^{-}\to n\bar{n}$ and several non-baryonic final states in the vicinity of the $N…
